孤岛工作面撤出支架时的顶板加固及撤出工艺

Roof Reinforcement and Withdrawal Technology of Isolated Island Working Face when Withdrawing Support

11210高水充填工作面作为孤岛工作面,末采阶段顶板压力大。采用锚网支护控制工作面顶板,撤架时利用掩护架保证撤架空间安全,利用移架平台撤出剩余支架,实现了安全生产。

The 11210 high water filling face is an island face,and the roof pressure is high in the last mining stage.The roof of the working face is controlled by anchor net support.When removing the frame,the cover frame is used to ensure the safety of the space for removing the frame,and the rest of the frame is removed by using the platform for removing the frame,so as to realize the safety production.
